Specification of Letters Patent.

Application filed September 16, 1911. Serial No. 649,658.

T 0 all whom it may concern.

a citizen of the United States of America,

residing at Favette City, in the county of Fayette and State ofPennsylvania, have in vented certain new and useful Improvements inCoinbination Tools,-ot which the following is a specification, referencebeing had therein to the accon ipanying drawing.

This invention relates to a combination tool, and more particularly to atool that can be used as a T-square, miter square, center square, bevelprotractor, level and plumb, and depth gage.

The primary object of my invention is to provide a combination tool otthe above type that can be easily and quickly adjusted for its varioususes, the tool being accurate and h ghly eilicient tor the variouspurposes for-which it is intended.

Another object of this invention is to provide a tool consisting ofcomparatively ifew pa ts that are strong and durable, inexpensive tomanufacture and easy to assemble.

lVith the above and other objects in view, the invention residesv in thenovel construction combination and arrangementof parts to be hereinafterspecifically described and then claimed.

Reference will now be h ad to the drawing, wherein Figure l is a. sideelevation of a portion of the tool, Fig. 2 is a sin'iilar viev: of thetool, partly broken away and partly in section, Fig. 3 is 1n cud view ofthe tool, Fig.

4c is a longitudinal sectional view of aportion of the blade of thetool, Fig. 5 is a horizontal sectional view of the tool, and Fig. 6 is across sectional view of the same.

A tool in accordance with this invention comprises a base 1 having; oneend thereot' provided with an angularly disposed arm 2, said arm beingpreferably disposed at fortytivedegrees relatively to the base 1. Thearm 2 is connected to the opposite end of the base by a leg 3 disposedat right angles to the arm 2, and between said leg, arm and base thereis a semi-circular web 4 providing an opening 5 and a segment-shapedslot 6. The base 1 has the bottom thereof provided with a V-shapedgroove 7, whereby the base can be easiiy placed upon a shaft or thetrawling edges oi two angularly disposed iriaces or --.v-.ilis., Sdilioove extending from one end of said base to the opposite end. The top ofthe base has a longitudinal groove or pocket 8 and in this groove orpocket there is located a level glass 9 retained within the pocket by astrap 10 secured to the top of the base 1.

At the vertex of the angle formed by the base '1 and the arm 2, there isa vertical slot 11 and this slot is in communication Jith thesegment-shaped slot 6 by an opening Adjustably mounted in the slot 11 isa blade 13. having a longitudinal slot 14 extending from one end thereofin close proximity to the opposite end, said slotv terminating in anopening if) for a purpose to be presently referred to. The opposite endof the slot is partially closed by a web 16 and there is another web 17.adjacent to the opening in order to add strength and rigidity to saidblade. Engaging in the slot 1.1 is the hoole shaped end 18 of aclan'iping member 19, said member extending through the opening 12 intothe slot (3. The member l-l ternii notes in a screw 20 to receive aknurled nut 21. The screw :20 has a transverse slot 22 providingclearance for a pin 23 arranged transversely of the opening 12, this pinlimiting the movement of the clamping member. Encircling the screw 20,Within the nut 2.1. is a coiled compression spring 2-11 and this springis employed tonernially retain the nut 21 tight upon the screw- 20,preventing said nut from becoming accidentally displaced. The thicknessof the blade 13 is less than the width of the slot 11, under suchconditions the blade can readily be placed in engagement with theclamping member. By loosening the nut- 21 the blade 13 can be adjustedwithin the slot 11 and when the nut 21 is screwed home the blade will befixedly maintained. at right angles to the lower edge of the base 1. m

-l 3.1;3 opening 15 is employed to enable the screw 29 to be fittedtherein when the blade 13 is Y used a protraetor.

' T he arm 2, at the upper end of the leg 3,

has a slot. 25 in parallelism with the base it, and said arm has a boss26 containing a clamping member similar to the member 19 previously boss26 being adjusted by a nut 2'2. The blade13 can be readily removed fromthe slot 11 and placed in the slot and therein by means of the ad' Thebase 1 is provided described, the member Within the 1 l ticked opening28 having the walls thereof'screw threaded to receive a screw 29 fromeither side of the base; and this screw when not in use is carried in athreaded socket 80 provided therefor in the base 1, opposite the slot11. The screw opening 28 is intermediate the ends of the level glass 9,and the screw 29 is employed for holding the blade 13 upon either sideof the base 1. With the blade upon one side of the base 1, it can beswung at any desired angle relatively to said base, the angle beingdetermined by graduations 31 upon the side of the web 4. It is with theblade in this position that the square can be used as a protractor.

It is obvious thatwith the blade adjustably attached to the base 1, thedevice can be,'used as a depth gage, and that by means of the levelglass 9, the level of a shaft or other structure can be readilydetermined.

It is thought unnecessary to describe the various uses of the tool, asartisans may em ploy the same for. various purposes.

.What I claim is '1. A combination tool comprising a base, a level glassmounted in one edge of the base, an-angularly disposed arm projectingfrom one end of and overlapping said base, said arm providedintermadiateits ends with a transverse slot 25 and further having-at oneend a longitudinal slot 11, said base having one end provided with aslot,.an inclined leg connecting the other end of said. base to said armintermediate the ends of the latter, a segment-shaped graduated webconnecting said leg and base and spaced i'rom said arm to provide anopening, a longitudinally slotted blade adapted to be mounted in theslot 25 and the slot at the end of said base,

; means arranged insaid opening and extending into the base and engagingin the slot of the blade for adjustably holding said blade' inengagement with one end of the base, and means arranged in said openingand extending into said arm intermediate the ends thereof and capable ofengaging in the slot of the blade for adjustably holding said blade inengagement with said arm the arm.

2. A combination tool comprising a base, a level glass mounted in oneedge of the base, an angularlydisposed arm projecting from one end ofand overlapping said base, said arm provided intermediate its ends witha transverse slot 25 and further having at one end a longitudinal slot11, said base having one end provided with a slot, an inclined legconnecting the other end of said base to said arm intermediate the endsof the latter, a

when the blade is mounted in the slot 25 of 5 0 segment-shaped graduatedweb connecting bladein engagement with said arm when the blade ismounted in the slot 25 of the arm, said blade provided at one end of itsa longitudinally slot with an opening, and means capable of extendingthrough the opening of the blade and engaging in the base for couplingthe blade to the base when the blade is to be used as a protractor.

In testimony whereof I aflix my signature in the presence of twoWitnesses.
